What does the Borg scale measure?

The Borg scale measures the rate of perceived exertion (RPE), which is a subjective assessment of how hard an individual feels they are working during physical activity. This scale typically ranges from 6 to 20, corresponding to a continuum of effort perceived by an individual, where lower numbers indicate lighter exertion and higher numbers indicate greater exertion. It is a valuable tool because it allows individuals to gauge their exercise intensity based on personal feelings of effort, discomfort, and fatigue, rather than relying solely on external metrics like heart rate.

Using the Borg scale enhances self-awareness during physical activity and can help guide individuals in regulating their intensity levels to match their fitness goals or medical recommendations, making it an essential component in lifestyle medicine and fitness training.
